Why low fermentation food checker matters

SIBO (Small Intestinal Bacterial Overgrowth) diets focus on reducing fermentable foods that feed bacteria in the small intestine. Low-fermentation foods help manage symptoms like bloating, gas, and abdominal discomfort.

  • Low-fermentation eating reduces food for overgrown bacteria
  • Meal spacing (4-5 hours) allows the MMC to clear the gut
  • Avoid grazing - structured meals are better
  • Some find the elemental diet helpful under medical supervision
  • Address underlying causes with your healthcare provider

What to know about miso paste

Miso paste is fermented soybean, and its deep savoury taste is a clue to its triggers. The long koji ferment builds free glutamate, which is the umami you taste and the reason miso reads like a natural MSG, and it also raises histamine and tyramine. On top of that the soybean base is high in GOS, a FODMAP, and many misos are cultured on barley so they are not reliably gluten-free. If a bowl of miso soup leaves you flushed, headachey or bloated, the fermentation and the soy are usually behind it.

Watch for

  • High in free glutamate from fermentation, the umami hit that can read like MSG for people who are glutamate sensitive
  • High in histamine and tyramine because it is aged for months, so it can drive flushing and headaches
  • High in GOS from the soybean, a FODMAP that can cause gas and bloating
  • Often made with barley koji, so it is not dependably gluten-free unless labelled
